EVAPORATI'NG APPARATUS.

Specification of Letters Patent.

Patented Dec. 23, 1813.

Application filed July 30, 1912. SerialNo. 712,242.

Todll whom it may concern Be it known that I, DoNA'ro Cozzomno, a sub ect of the King of lltaly, and a resident -of San Diego, in the county of San Diego and State of California, have invented a new and Improved Evaporatin Apparatus, of which the following is a fu I, clear, and exact description.

The invention relates to apparatus for dealcoholizing', condensing,evaporating or distilling liquids, such as beer, ale, stout, malt extracts and the like," and semi-liquids, such as crushed fruit, jams, crushed vegetables and the like.

The object of the invention is to provide a new and improved evaporating apparatus arranged to facilitate the evaporation of a liquid or a semi-liquid by the 'use of suspended surfaces having their loud)- portioi'is extending into the liquid and ha 'ing their upper portions above the level of the liquid, so that in case the liquid is fed into the vessel. from above it flows down the surfaces and hence readily evaporates, and in case the surfaces are of fabric material the liquid contained in the lower portion of the vessel passes up the surfaces by capillary action and is then evaporated.

A practical embodiment of the invention is represented in the accompanying: drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a sectional side elevation of the evaporatingapparatus on the line l l of Fig. 2; Fig. 2 is a sectional plan view of the same on the line 2-2 of Fig. 1; Fig. 3 is a perspective view of one of the surfaces and its supporting, grate; and Figs. 4 and 5 aresectional side elevation of modified forms of the evaporating apparatus;

The evaporating vessel A is adapted to contain the liquid or semi liquid to be dealcoholized, condensed, evaporated or distilled, and the upper end of the vessel A is provided with an outlet 13 connected with a vacuum pump or other means for producing a vacuum in the vessel A. The liquid contained in the vessel A is adapted to be beated either by a steam coil placed in the said vessel, orby the use -'of a hot water water jacket C, as indicated in Fig. 1.

Within the vessel A are suspended series of evaporating surfaces, each series being formed of a plurality of spaced sheets D, preferably of a fabric material such as burlap, linen or the like, and the sheets D of a series are attached at their upper ends to cross bars E of a grate E provided with a hook E adapted to be hooked onto a cross bar F extending within the upper portion of the vessel A, and secured at their ends to the wall of the vessel A. The lower end of each sheet I) i provided with a suitable weight G to hold the sheet in a vertical position so that the lower port-ion of each sheet extends within the liquid or semi-liquid contents of the vessel A, while the upper portion of each sheet D is above the level of the said liquid contents. It will be noticed that when the apparatus is in use the liquid or semi-liquid contents in the vessel A readily pass up by capillary action in the sheets D,

and when above the level of the liquid, the liquid contents in the sheets readily evaporates. By providing a large number of sheets suspended within the vessel A as described, it is evident that a large evaporating surface is provided to insure a very 'apid evaporation of the liquid contents of the vessel A. The sheets 1) may be of other material, such as metal or earthenware, wood or clay in case the liquid or semi-liquid is fed into the vessel A from above, so that such liquid flows down the sheets 1) in very thin sheets, to insure rapid evaporation of the liquid. 1'.- is understood that by providin; a very large evapo 'ating surface within the vessel A, the quicker the evaporation takes place.

The vessel A as shown in Figs. 1 and 2 is made in two sections fastened together, and both sections are providedwith suitable manholes H and H and the upper section is provided with a valved inlet] and peep holes J and the bottom of the lower section is provided with a valved outlet K.

in the modified form shown in Fig. 4 the vessel A is in the form of a cylinder and in it is suspended evaporating surfaces D extending at their lower ends in the liquid. The upper end of the vessel A is provided with. an outlet B for the vapors, and intermediate the upper ends of the surfaces 1) and the top of the vessel A is arranged a perforated partition L forming a retarding and straining plate. The top of the vessel is provided with an inlet I and'near the lower end of the; vessel to maintairi the liquid at a desired level in the vessel. A steam inlet N. isconnected with the vessel. A a distance abovethe outlet is arranged an outlet K' B. Feep holes 5 are locate-ti in vessei A opposite the upper 02 tile surfaces D.

in she modified form shown in Fig, evaporating vessel is made in the form of Iiumoe? of sections A A and A one on to; of the other anci separated by pariitious a'ii l 0 provided with overflow maintain the iiqui "so be evaporated desired heigiis the sections A aiiei to aliow the vapors to pass from section to theone next above. The top section A* is provided wish ehargiug inlets I and vapor outlet B and the lower section A is oi'ovirieci with an outlet 15. a diseases above the bottom of tee section is maintain the liquid at a desired level in 'tiiis section. Within each section A suspendeci the evaporating surfao s U2 simiiar ":0 the evaporating surfaces D and above described. Peep hoies J are in each section A A? and A opposite the uppei'eiids of the surfaces B A perforate retarding aini straining plate if similar to plate L is arranged in the uppei" section it, and she lower section A is provided with steam isles N". Steam pipes P conduct toe steam from one compartment the otLer and have reiurii bends submei'ge in the liquid in the corresponding compartment A? or A The action that takes place in the ape-aratus shown in Fig. l and 5 ispractioally the same as the one above described in reference to toe apparatus shown in Figs. and 2.
